Journal of Medical Physics and Biophysics is a gold open-access journal and serves as official publication media of the Indonesian Association of Physicists in Medicine, IAPM (Aliansi Fisikawan Medik Indonesia, AFISMI). JMPB publishes articles with the general concern on the application of physics in medicine and the biological system. The role of physics highlighted in the journal can be of theoretical, experimental, or clinical nature. Review and original articles in radiation oncology, diagnostic and interventional radiology, nuclear medicine, biomaterial, physical biology, physical modeling of biological system, and other related sciences are welcome. Any opinions stated on the articles published in JMPB are those of the author(s) and do not necessarily reflect the policy of IAPM/AFISMI unless otherwise stated.

Abstract

Gamma radiation is ionizing radiation causes cells damage. It was caused by interaction of radiation with cells can produce free radical. The cell defense mechanisms againts free radical involves an antioxidant that can neutralize and catch it. The objectives of this research were to analyze effects of gamma radiation exposure and treated with Curcuma xanthorrhiza extract in central vein to the mice’s liver. Eighty mices were used in this research and divided into three groups, negative control (K-), radiation non extract (R-) and extract plus radiation (R+). The mice were treated with 1.4; 2.0; 2.6; 3.2 and 3.8 gr/kg body weight. The exposure of gamma radiation are given during 10, 20, 30, 40 and 50 minutes. The measuring of central vein area is done by observated microscopic picture mice’s liver. The results showed that free radical forms lipid peroxidation that causes necrosis to the liver cells, one of them is widening of central vein. The treatment with Curcuma xanthorrhiza extract can prevent the enlargement of central vein with increasing Curcuma xanthorrhiza extract dosage, from 129424 µm2 menjadi 12941 µm2. Curcuma xanthorrhiza extract contains curcumin that can inhibit forming free radical because of gamma radiation to liver.

Abstract

Alzheimer's Disease (AD) is a neurodegenerative disease characterized by decreased memory function and cognitive ability. The disease is caused by damage to neurons due to the accumulation of amyloid beta plaque (Aβ) and neurofibrillary tangles (NFTs) within the neurons. This condition causes the transmission of electrical signals in the brain to be inhibited and there is a change in the level of irregularity and complexity of brain signals. The purpose of this study was to measure the degree of irregularity and complexity of EEG data in AD patients with spectral entropy and Largest Lyapunov Exponent (LLE) quantities. EEG data recording uses 14-channel Emotiv Epoc with a sampling frequency of 128 Hz. The test subjects consisted of 9 subjects with Alzheimer's Disease and 10 control subjects. The Mann-Whitney U test statistic was used to see if there were significantly differences in the values of spectral entropy and LLE between the AD group and the control group. Based on the calculation results obtained that the value of spectral entropy of AD patients lower than control subjects (p <0.05) on P8, F4 and AF4 electrodes. The chaotic level test with LLE showed significantly difference (p <0.05) on AF3, F7, FC5, P8, T8, F4, F8 and AF4 electrodes between AD group and control group. The study of EEG nonlinear dynamics can be used to determine the degree of irregularity and complexity of brain signals.
